Name=Sonar
Comment=This draws a sonar screen that pings (get it?) the hosts on your local network, and plots their distance (response time) from you. The three rings represent ping times of approximately 2.5, 70 and 2,000 milliseconds respectively.  Alternately, it can run a simulation that doesn't involve hosts.  http://en.wikipedia.org/wiki/Ping#History  Written by Jamie Zawinski and Stephen Martin; 1998.
